DETROIT — One of the many dominoes after the Prince Fielder-Ian Kinsler trade is the Detroit Tigers now need a new first baseman.

Which also could open up a spot for their top prospect in the 2014 lineup.

With Fielder gone to the Texas Rangers and Detroit receiving second baseman Ian Kinsler in return, Tigers president Dave Dombrowski noted it's certainly a possibility that two-time MVP Miguel Cabrera shifts back to first base and Nick Castellanos could get a shot at playing third.

"That's something we need to discuss," Dombrowski said late Wednesday night on a conference call. "We really haven't talked to (Cabrera) about going back to first base. You think of him at some point needing to go back over."

As for Castellanos, Detroit had shifted the former shortstop to the outfield when it became apparent his path to the majors could be blocked by Cabrera and Fielder.

Castellanos shifted to third base during his first professional season with the West Michigan Whitecaps in 2011, and Dombrowski said he's still been taking ground balls there despite not playing third in the field in 2013.

"I would think he can make the transition pretty quickly if that's what we decide to do," Dombrowski said. "We had talked about the possibility this happening. We weren't anticipating it happening necessarily so quickly."

If Castellanos isn't ready begin the season in Detroit, the Tigers could keep Cabrera at third base and Victor Martinez could play first.

"(The trade) gives us some flexibility at the first base/DH spot," Dombrowski said. "I'm really not sure what we're going to do as we sit here today."
